Lutein – keeping your eyes healthy

Regardless of what you call, little seems to be important to human health.

One of the reasons why researchers can not agree on what they call lutein are not sure whether life is needed, in small quantities, or just have a beneficial effect on good health. In the absence of food deficiencies are associated, though one of the carotenoids.

Carotenoids turn into vitamin A in the human body. Vitamin A needs life. Food shortages first cause harmful vision, usually night blindness.

Occasionally, the cornea dies and is the result of complete blindness. If the deficiency is not corrected, the upper respiratory tract and the bladder lining will be hard. Death can be a result.

The blindness caused by vitamin A deficiency can not be remedied. But if thinking in the early stages, vision is restored. Even night blindness disappears.

There has always been concern with additives that contain the animal form called retinol called vitamin A. Retinol is toxic in large doses. The body can not get rid of it.

Carotenoids, on the other hand, are not toxic.

Lutein is also important in vision because it is an element of the retina, an area within the eye that transmits signals to the brain and allows you to see it. Together with zeaxanthin, this primary pigment is within the retina.

The Zeaxantin ("Zee-a-ZAN-thin") concentration is the highest in the macula, which is located in the central vision retina. The peripheral retina is the highest concentration of lutein, where peripheral vision occurs.

Macula's disease called macular degeneration, which often causes blindness. At one time, they were simply thought to be age-related illness.

But more and more evidence suggests that it is a "dietary disease".

Typical American diet includes a number of elements that contribute to the disease. Too much animal fat, not enough vegetables, low nutrition and high calorie intake. Many people never receive the micro-nutrients present in plants because they have been cut off.

But today, even the best dieter, can put these micronutrients into trouble. Studies have shown that fresh fruits and vegetables are not as nutrient-rich as before, primarily because of overproduction.

Researchers continue to gather evidence of the importance of micronutrients in the identification of blood levels who are suffering from a special disease.
